It is important to know that you need aircon repair when you experience these air conditioning problems.
The air conditioning doesn’t turn on
You should check the thermostat batteries when the air conditioner is not working or not turning on. You can replace the batteries if it is no longer working. If the batteries are in good working condition, check the thermostat settings to know whether the cooling mode works according to your desired temperature settings.
When the thermostat is on, and the AC is still not turning on – check the circuit breaker. When the circuit breaker is tripped, the air conditioner will not turn on. Reset the circuit breaker by flipping the switch off and on.
AC is not blowing cold air
The air conditioner will not blow cold air if the dirty filter will block the airflow of the unit. The dirty air filter frees up the condenser unit and will limit the cooling power of the AC. Changing the air filter each month helps your air conditioning unit blow cold air.
AC freezes outside the unit!
An air conditioner freezes up due to some reasons:
- Blower motor problems
- Insufficient airflow
- Low coolant levels
- Low outside temperature
- Stuck contractor
Air conditioner refrigerant leak
When the coolant in the air conditioner starts the leakage, the temperature varies, and the unit will not function accurately. The refrigerant leaks result in the following:
- Low efficiency
- Damaged compressor
- Coil freezing
- Uneven cooling
- Coil freezing
Inspect the air conditioner regularly for possible refrigerant leaks.
The air conditioner makes noises
An air conditioner makes different sounds, it depends on the type of problem. The different reasons why the air conditioner produces various sounds:
A refrigerant leak produces a hissing sound
Once you hear the clicking sounds when turning on and off the AC, it can be a relay problem

- thumping
- rattling
- banging
- The faulty electrical components make a buzzing sound
Frozen evaporator coil
The evaporator coil can freeze when the air conditioner doesn’t receive sufficient air needed for the operation. The frozen evaporator coil makes the AC freeze up and stops working. There can be reasons why AC experiences insufficient airflow in the system, such as:
- Blocked vents and ducts
- Dirty filters
- The faulty fan
A clean air filter maximizes airflow and indoor air quality.
These are just a few of the AC problems that need aircon repair.
